If angle T and angle V are adjacent angles & complementary, and the measure of angle T is 60º, what is the measure of angle V?
What is 30º?
If angle A and angle B are complementary angles, and the measure of angle A is 35º, what is the measure of angle B?
What is 55º?
If angle K and angle L are supplementary angles, and the measure of angle L is 105º, what is the measure of angle K?

True or False: Vertical angles cannot form a linear pair.
What is true? They can't form a linear pair because a linear pair has to share a side and be adjacent. Vertical angles could be supplementary though (90 + 90)!
If angle T and angle V are adjacent and supplementary angles, and the measure of angle T = (x)º measure of angle V = (2x)º Find the measure of angle V.
